odt writer does not apply custom styles for characters, blocks and so on

[N0rbert]

I'm using pandoc 2.7.3 to produce some bookdown documents.
I know that custom styles and styles reference works normally in docx (at least for paragraphs).
But it does not work for OpenDocument.

I have the following simple Markdown document named styles.md. It use predefined style names from LibreOffice 6.2 and contains the following:

::: {custom-style="Title"}
This is some text.
:::

::: {custom-style="Caption"}
This is text with an [placeholder]{custom-style="Placeholder"} text style.
And this is text with a [teletype]{custom-style="Teletype"}
text style.
:::

::: {custom-style="Illustration"}
> Here is a styled paragraph that inherits from illustration style.
:::

I expect that the document should look as shown below:

But if I produce OpenDocument from my Markdown document it with pandoc styles.md --to odt+styles -o styles.odt. The styles are not applied:

Judging from the manual, custom_styles is only currently implemented for docx and icml.

In anyway it would be very useful to have described functionality inside pandoc itself. This means without plugins and third-party tools. This will make pandoc even better. Having this functionality only for docx is unfairly.
